Question about N.nivea color forms

Guest

Hi there,

I've got a question upon the color forms of N.nivea. We know that they have a lot of different possible colours (yellow, yellow with blakc, orange dots, brownish, almost black, etc).

I've been recently talking with someone who went to take over some specimens about 25 years ago in south africa. He told me that in a definite biotope (zone) he could find different colours of the N.nivea. He was saying to me that the colours were NOT a factor of specific provenance.

My question is about if it's verified that the colour are not a factor of specific provenance (like as an example different shape of colours by the B.arietans tanzania, etc)? Other question if this is verified, what colour would be recessive? Because if we got a mixity of colours, there should be, time after time, one dominant colour...??

Has someone ever bred to complete different type of N.nivea together (as example brownish and yellow?)?

I'd be glad to have some more infos about that.

thanks a lot!

Cheers

Yes, I did for the last 15 years...
The breeding male's almost uniform yellow, with just a few brown spots, and the female's vice versa, unform dark brown with a few yellow spots.
Offspring turned out (after one or two years) to be very different: Almost completely yellow specimens, like the father is, almost completely brown or dark brown specimens, a few of'em completely black with yellow spots, another few with a grey ground colour.
I don't believe the "genetics" of the different colours to be recessive, dominant or co-dominant, but intermediate.
Very surprisingly, ground colours and presence or at least amounts of spots can change in adults during their lifetime.
My breeding male's sometimes uniform yellow with almost no spots, sometimes brown-yellowish and heavily spotted.
Unfortunately, I don't have any records to proof the dependence of this phenomenon on seasons or reproduction cycles.

Thanks a lot Peter for the information... Do you got some pictures of the youngsters that you had? And of your adults?

Thanks a lot

Youngsters look always the same, yellow or brownish-yellow, sometimes with numerous small specklings, always with black throats.
I'll ost some pictures of adult specimens within the next days.

Excuse me for my mistake, I meant, the youngsters that grown up... Embarassed

Of course the young Naja nivea have effectively the black throat and a yellow body qith small specklings... I have some pictures of my young Naja nivea.

Thanks a lot Peter!
